## About

Founded in 1879, Saint Mary's Hall began under the auspices of the Episcopal Church and has since operated as an independent, coeducational day school serving students from age three through 12th grade. The school moved to its current 60-acre campus on Starcrest Drive in San Antonio, where it runs a liberal-arts curriculum, Montessori lower school, and college-preparatory upper school. The endowment exists to supplement tuition revenue and fund capital projects, faculty development, and financial aid. The endowment portfolio reflects the influence of a board that includes executives with direct investment backgrounds. Randall Mays, Co-Managing Partner of Mays Family Enterprises, and Jason Glast, founder of a residential real estate group, both serve as trustees, according to firm records. While the school does not publicly disclose its asset allocation, the investment strategy documented in Altss research spans buyout, venture capital, growth equity, natural resources, and fund-of-funds commitments — a range more commonly associated with family-office or pension portfolios than with a single independent school. Co-investors and supporters tied to the endowment program include Carlos Alvarez, founder of The Gambrinus Company, and Erin M. Baker, a senior managing director at Guggenheim Partners. The school maintains association memberships through the Independent Schools Association of the Southwest and the National Association of Independent Schools, and its athletic teams compete in the Southwest Preparatory Conference. In late 2024, Saint Mary's Hall concluded a nationwide search and appointed Dr. Avé Luke-Simpson as Head of Middle School, bringing more than two decades of independent-school leadership experience from Headwaters School in Austin, per the firm's own announcement. The endowment functions without a separate external investment office, with oversight provided through the board's finance and investment committees. A genuine structural differentiator is the endowment's ability to lever the alumni and trustee networks typical of an elite Texas K-12 institution to source institutional investment opportunities. Notable alumni including Sardar Biglari, founder and CEO of Biglari Holdings, create a funnel of operator-adjacent capital-formation relationships that few comparably sized endowments can replicate.

## Questions

### Who runs investment decisions for the Saint Mary's Hall endowment?

The endowment is governed by Saint Mary's Hall's Board of Trustees, which includes members with direct capital-allocation responsibilities outside the school. Randall Mays, Co-Managing Partner of Mays Family Enterprises, and Jason Glast, founder of a real estate group, are both trustees who bring investment-committee experience, according to Altss research. The school does not list a dedicated chief investment officer.

### Who are the notable alumni or supporters connected to the endowment program?

Several individuals with significant investment industry profiles are linked to the Saint Mary's Hall community. Sardar Biglari, founder and CEO of Biglari Holdings, is a notable alumnus. Carlos Alvarez, founder of The Gambrinus Company, is a significant endowment contributor, and Erin M. Baker serves as a Senior Managing Director at Guggenheim Partners, per Altss research.

### Is the Saint Mary's Hall endowment managed externally or internally?

The endowment does not maintain a separate external investment office. Oversight rests with the school's Board of Trustees, specifically through its finance and investment committees. This internal governance structure relies on the professional investment networks of its board members to source and vet opportunities.

### Does Saint Mary's Hall participate in any regional or industry consortiums?

The school itself is a member of the Independent Schools Association of the Southwest (ISAS), the National Association of Independent Schools (NAIS), and the Southwest Preparatory Conference (SPC). These affiliations can offer ancillary networking channels with peer institutions and their own endowments, though they are not investment-specific consortiums.
